ADJUSTABLE WNDOWSCREEN.

.appiieatien fusa reti-nary ia, serial esatte.

To all whom 15 may concern Be it vknown that we, SAMUEL Gf. Fosrnn, a citizen of the United States, residing at Westfield, Union county, and SAMUEL A. Fos'rnn, a citizen of the United States, residing at Rahway, in the county of Union and State of New Jersey, have invented certain new and usefuly Improvements in Adjustable Window-Screens; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved adjustable window screen.

The main object of the invention is to provide a window screen composed 'of a single sheet of woven wire which may be adjusted to fit windows of varying sizes.

Another object of the invention is to provide a screen, the side and end members of the frame of which are adjustable in planes at right angles to each other to change thel shape and dimensions thereof, the woven wire fabric being automatically adjusted simultaneously with the frame.

With these and other objects in view theJ invention consists of certain novel features of construction, combination and arrangement offparts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a front elevation of this improved' screen shown extended to its extreme width in full lines and retracted to its narrowest width in dotted lines; Fig. 2 is asimilar view with the parts in the position the assume when in the dotted line position o Fig. 1; Fig. 3 is a ltransverse section taken on the line 3--3 of Fig. 1; Fig. 4: is an enlarged detail vertical section through one corner of the` screen;

Fig. 5 is a front eleva'tion'of a slightly modiiied form of the invention; Fig. 6 is a per spective view of one of the wire securing clips detached.

In the embodiment illustrated a frame is shown composed of four slidably engaged right angular members 1, 2, 3 and e which are preferably composed of L-sliaped tubular sections telescopically engaged and slotted longitudinally on their inner sides as shown a-t 5 to receive the loosely woven screen wire .6 which is of rectangular' shape and loosely secured thereto in any suitable manner.

Specification or Letters Ltatent.

This sheet of screen wire is cut 'with the strands of wire running diagonally or on the bias and preferably from a sheet of galvanized screen wire fabric of any suitable mesh the wires forming said fabric being unsecuredat their points of intersection. rPhe edgesnf this sheet areV inserted in the slots 5 of the frame members and are secured to the corners of said members by screws or rivets as 7 which extend? transversely through the frame members and the wire. Clips as 8 preferably constructed in the form shown in F igs. 3f and 6 are mounted in the free ends of the arms of the members 1 and 3. Thel circular intermediate portion 9 of these clips fits snugly within the tubulararms or sections of the frame members andthe parallel arms l() and 11 of said clips extendon opposite sides of lthe screen wire 6 and are secured thereto by' lrivets as 12 which extend through alined' apertures as 13 in said arms 10 and-11 and through the screen wire thereby holding said" clips in the saine position relative to the wire during the sliding movementof the` frame sections.

In the form shown the telescopically engaged L-shaped sections are preferably coiinected by engaging the short arm ofv thesecv` tion 2 with the long arm of section 1, said long arm sliding in said short arm andthe long arm o f section 2 slides over the short'nlp..v arm of section 3 and the long arm of sectioiij-z 3 slides within the short arm of sectionv ll,`be-

members 1 and 3 and -prevent further ex-lr-" pansion of the members. Vifhenl the -t'elescoping sections are adjusted the strands of the screen wire are shifted, said shifting be-y ing permitted by reason of the diagonal arrangement of the wireI threads forming the mesh and the loose connection of the cut'.`

edges ofthe fabric with thel frame sections. V

In lthe use of this device when' the upper and lower ltelescoping members aremovcdj outwardly relatively to eaclihotherthe simil' u@ larly engaged side members are moved in- L shown in Fig. 2, thus'as 'the'.width- .of the screen is reduced the height isincreased vand vice versa, the strandsfof the screen shifting as the frame members slide on eachother.

By this construction a screen may be obtained having a single unwrinkled sheet of screen wire, the frame and wire being adjustable in planes at right' angles to each.

,other to vary the length and breadth of the screen and in which there are no spaces for This screen whenI the entrance of insects. contracted has no. doublethicknesses or folds of wire to obstruct the passage of the air.

` In the form shown in Fig. 5 the screen is constructed in' thesame manner as the form above described except that .two bracing or guiding members 14 and 15 are shown in the form of wire rods arranged I diagonally across the screen and connected at their 0p'- posite ends with the diagonally opposite cornersof the screen being pivotally.- connected therewith. These rods are also pivotally connected with each other at their crossing point and they serve to hold the sections in the proper relation to leach other during the adjusting of the frame and thereby bracing the frame and reinforcing the screenwire.

'iFrom the foregoing description taken in co nection with the accompanying drawthe'construction andoperation of the invention willbe readily understood without requiring a more extended explanation. Various changes in the form, proportion and theminor details of construction may be resorted to without .departing from the princip e or sacrificing any of the advantageso' the' invention as dened in the appended claims.- We claim as our invention:

2. A Window screen comprising an adjustf able frame having a single-sheet of screen fabric loosely connected therewith and the ,strands of said \fabric being 'disconnected relatively to each other to permit said 'frame and'fabric to be adjusted'A together in the` same directions in planes at right angles to vary't'he length and ybreadthy ofthe screen. 1 adjustable window screen compris- 'i i ing a' ame, composedifof sections adjustably connected to varyy the "dimensions of. the
